Understanding Accelerated Learning Across Secondary and Postsecondary Education (pdf)
This brief from the College and Career Readiness and Success Center at the American Institutes of Research (AIR) "catalogs accelerated learning options that are currently being implemented in schools and highlights efforts made both within and across secondary and postsecondary education."
Accelerated learning options at the secondary level include credit recovery, double-dosing, the Talent Development model and the Diploma Plus program.
Postsecondary options include concurrent and dual enrollment, early college high schools, advanced coursework for college credit, Tech Prep, the FASTStart program, Academy for College Excellence, and the Integrated Basic Education and Skills Training (I-BEST) program.
Credit by exam options, where students take an exam to show that they have mastered course content without taking the course, may be available at both the secondary and postsecondary levels.
